Abstract

 

Observations on 193 Harvard plates confirm that RU Sex is an RR Lyrae Variable. A period search by discrete Fourier transform found candidate periods near 0.26, 0.35, and 0.54 day. Analysis of the times of maxima and phased light curves indicates that the best period is 0.3502323 day. The periods near 0.26 and 0.54 day are aliases differing in frequency by one cycle per sidereal day.
